What Are the Factors of 1000?

The factors of 1000 are 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 125, 200, 250, 500, 1000.

Calcating the factors of 1000 is straightforward. 1000 and 1 are the easiest two factors to find.


  1. Try 1. 1 x 1000 = 1000, so put these into our factor list.
    1...1000

  2. Take 2. 2 x 500 = 1000, which means we add these to our factor list.
    12...5001000

  3. Now take 3... no. 1000/3 isn't a whole number. So we skip 3.

  4. Next try 4. 4 x 250 = 1000, so we add these to our list of factors.
    124...2505001000

  5. Now try 5. 5 x 200 = 1000, so put these into our factor list.
    1245...2002505001000

  6. Try 6... no good. 1000/6 isn't a whole number. So we skip 6.

  7. Take 7... no. 1000/7 isn't a whole number. So we skip 7.

  8. Now take 8. 8 x 125 = 1000, so we add these to our list of factors.
    12458...1252002505001000

  9. Next try 9... nope! 1000/9 isn't a whole number. So we skip 9.

  10. Now try 10. 10 x 100 = 1000, which means we add these to our factor list.
    1245810...1001252002505001000

  11. Try 11... no. 1000/11 isn't a whole number. So we skip 11.

  12. Take 12... no luck. 1000/12 isn't a whole number. So we skip 12.

  13. Now take 13... nope! 1000/13 isn't a whole number. So we skip 13.

  14. Next try 14... no good. 1000/14 isn't a whole number. So we skip 14.

  15. Now try 15... no. 1000/15 isn't a whole number. So we skip 15.

  16. Try 16... no luck. 1000/16 isn't a whole number. So we skip 16.

  17. Take 17... nope! 1000/17 isn't a whole number. So we skip 17.

  18. Now take 18... no good. 1000/18 isn't a whole number. So we skip 18.

  19. Next try 19... no. 1000/19 isn't a whole number. So we skip 19.

  20. Now try 20. 20 x 50 = 1000, so we add these to our list of factors.
    124581020...501001252002505001000

  21. Try 21... nope! 1000/21 isn't a whole number. So we skip 21.

  22. Take 22... no good. 1000/22 isn't a whole number. So we skip 22.

  23. Now take 23... no. 1000/23 isn't a whole number. So we skip 23.

  24. Next try 24... no luck. 1000/24 isn't a whole number. So we skip 24.

  25. Now try 25. 25 x 40 = 1000, so put these into our factor list.
    12458102025...40501001252002505001000

  26. Try 26... no good. 1000/26 isn't a whole number. So we skip 26.

  27. Take 27... no. 1000/27 isn't a whole number. So we skip 27.

  28. Now take 28... no luck. 1000/28 isn't a whole number. So we skip 28.

  29. Next try 29... nope! 1000/29 isn't a whole number. So we skip 29.

  30. Now try 30... no good. 1000/30 isn't a whole number. So we skip 30.

  31. Try 31... no. 1000/31 isn't a whole number. So we skip 31.

  32. Take 32... no luck. 1000/32 isn't a whole number. So we skip 32.

  33. Now, since we don't have any more numbers to try, we're done!
